Title: Method and device for reproducing optical recording carrier
Inventor: SAITO MIKIKO
IPC: G11B7/26
Filed: 1989-10-25
Abstract: PURPOSE:To prevent the contact of UV curing resins and the intrusion of bubbles at the time of spreading by applying the resins on both of a die stamper surface and a transparent substrate and warping the transparent substrate so as to curve with respect to the die stamper. CONSTITUTION:The UV curing resins 3a, 3b are applied circumferentially in the middle circumferential part of the surfaces of the transparent substrate 4 and die stamper 1 which are installed horizontal. After the substrate 4 is turned over, the substrate 4 is placed on a substrate supporting jig 8 and the registering and centering of the stamper 1 and the substrate 4 are executed. A weight 7 as a jig for curving and holding the substrate 4 is then placed on the central part of the substrate 4 to curve the substrate 4. The UV curing resins 3 spread concentrically when the substrate 4 is brought near to the stamper 1. The weight 7 is removed and the jig 8 is moved and pulled from the outer periphery. The substrate 4 descend slowly at this time. The entire part of the substrate 4 is thereafter pressurized to develop the resins to the desired outer and inner peripheral regions. The resins 3 are finally irradiated with UV rays from the substrate 4 side and are thereby cured.

Abstract: PURPOSE:To contrive to improve the reliability of wiring by preventing the increase in contact resistance of the titled device, by a method wherein the insulation film in the periphery of a contact hole is fused into a taper by heating the substrate surface. CONSTITUTION:Gate electrodes 15a, 15b are formed on top of a P-type Si substrate 11. Next, N<+> source and drain regions 16, 17 as N-type diffused layers are formed; then, P<+> source and drain regions 18, 19 as P-type diffused layers are formed. Further, an SiO2 film 20 as the interlayer insulation film and a phosphorus-doped glass film 21 as the low-temperature fused insulation film are formed over the whole surface. Contact holes 22 are formed by selectively etching the portions of the insulation film each corresponding to the N- and P-type diffused layers. The whole substrate is coated with a Ti film 23, which is thereafter made to react with the Si in the substrate 11 by heating the substrate 11, resulting in the formation of a Ti silicide layer 24. Finally, the substrate surface is heated. This process makes the glass film 21 fused into a taper A at the contact hole part and other step parts, leading it to flattening.
